Ok, so Pinto rack. Obviously, if the pressures are right and you say they are, their racks are junk. If I were you I would make sure there's nothing custom about it, that it IS a bonifide Pinto/Rustang II rack. If it is, send that POS back and get a run of the mill reman from like Autozone. But get a good brand reman. A1 Cardone for instance. They bore out their reman racks and press a steel sleeve into the rack. They generally last a long time.
